Application inea June '6, 1923. serial No. 643,794.

To all whom t concern.'

ments have been made at the ends of the slice and the minor,l closer, adjustments have been made at the jointures by moving the plates relatively to-each other.

One of the main objects of my invention is to provide a suitable slice composed of a main member or part which has one or more complementary pieces bolted thereto. The slice 'so provided is supported at its ends by the deekle'frame and has a flexible bar constituting a lip mounted on its lower edge whichpreferably is also made in sections corresponding in length with said part v and complementary piece. I also provide means for flexing the bar relatively to the apron board so as to neutralize uneven lstrata in the flow `of the stock and thus cause such flow to become uniform throughout its width.

A further object is to provide a slice which is made up of a plurality of pieces which are rigidly bolted together, with the ends of the adjoining pieces. overlapping each other. Thus I provide an efficient' slice capable of being arranged to run different widths of paper.

I attain my lobject in a paper maklng'machine having two deckle frames spaced apart, relatively adjustable towards and from each other, anda slice supported between them, vsaid slice consisting of a main part of lesser length than the space between said deckle frames in one of their adjustments, a removable complementary. lhng piece carried by one end of sald vmain part to make the length of the slice correspond with said space,`a flexible lip adjustably secured to the lower .edges of said main part of thevslice and said complementary piece. I also preferably provide on that end, of

- the slice to which said complementary piece is alixed, an arm of substantial width, thereby firmly holding the slice in yvertical almement, such arm' extending across the complementary piece to the adjacent deckle frame. I also preferably make the exible. lip 1n sections. which correspond in length with the respective lengths of the main part and said complementary piece.

The construction and operation of my improved slice I have illustrated in the accompanying drawings in which:

Fig. 1 is a plan view of my improved slice mounted in position between two deckle frames. l

Fig. 2 is an elevation of m slice with one type of flexible ip mounted on its lower edge, the deckle frames and deckle straps being shown in section.

Fig. 2a is a fragmentary elevation of and Fig. 2b is a vertical section througha slice embodying my invention which has a different type of flexible lip, these views being merely diagrammatic.

Fig. 3 is a-fragmentary view of one end of my improved slice taken approximately on a line of 3 3 of Fig. 5 and shows how my improved slice is horizontally and vertically adjustable and supported by the deckle frames.

Fig. 4 is a fragmentary plan view of one end of my improved slice in place and shows a vportion of a deckle frame.

Fig. 5 is a fragmentary side elevation of a deckle frame and the adjacent end of the slice, saidview being taken in the direction of the arrows in Fig. 3, and shows the mechanism by which my improved slice is adjustably supported in the deckle frames.

, 7 0 improved Fig. 6 is a section taken on the line 6-6 of Fig. 3.

Fig. 7 is a section taken on the line 7-7 of Fig. 3 which is through the jointure between the main portion of the slice and the complementary section.

F1g.8 is a section taken lon the line 8-8 of Fig. 3 which is through one of the adjusting rods for the exible lip.

Fig. 9 shows complementary fragmentary perspective views of one end of the main part of the slice, of the related complementary piece, and of the related sections of the flexible li which are mounted on the bottom edges o the said slice parts.

My improved slice is mounted transversely across a paper machine7 a part of which is shown as 1, between the two deckle'frames 2. It is mounted over the apron board 3.

and is vertically adjustable in the deckle frames sothat the space 41 between the apron -board and the edge of the slice proides an aperture through which stock can* As is common, a quantity of paper stock is held in a head box 4, the slice and the two deckle frame side plates2 constituting three sides of the box. It is necessary therefore that the slice fit snugly against the deckle frames so as to prevent leakage between the deckle frames and the ends of the slice. Leakage would spoil the formation of the paper stock flowing through. the aperture 4a b'etweenthe slice an board 3. j

Paper machines are made" so that the deckle frames may be adjusted inwardly and outwardly so as to vary the width` of the sheet of paper formed by said paper making machme. The slice necessarily must fit snugly against the deckle frames, andthus' means must be provided to correspondingly vary the length of the slice so as to accommodate said movement' inwardly and out: wardlyof the side frames. l A

In my improved slice I have provided a one piece slice 5 which is as long as the narrowest adjustment of the sideframes.

Offset supports 6, mounted in boxings 7 in the deckle frames, adjustably support said slice across the paper machine.' When it is desired to make wider sheets of paper, complementary pieces 5 may be used to fill out the space between the end of the slice 5 and the adjacent deckle frame 2. The joint between `the complementary piece 5a and the main section of the slice 5 is preferably stepped or overlapping as at 8, so -as to prevent stock in the head box from passing readily through Vthis jointure. The comple-` vmentary piece is fastened securely to the main piece of the slice 5 by screws which may be passed through the holes 9. Guide lugs 1() on the-complementary piece, interlock with complementary blocks 11 on the deckle frames and cooperate with the supportingboxings 7, to hold the slice in vertical alinement. The offset supporting portion 6 at each end of the slice, is fastened to the main member 5 of the slice by means of bolts 12 and is mounted so as to have horizontal adjustment in the -boXings 7 said boxings 7 are vertically adjustable and are held invertieal alinement .by guiding li s 7 fastened to the deckle frames. Each o the boxings `'i' has an integral threaded rod 13 mounted in the adjusting nuts 14 by which the boxing andy therefore the slioe can be adjusted vertically. The adjusting nuts 14' 'are supported between two ears 15 on the sidej frames, which prevent any play in the adjusting means. It is to be noticed that the complementary pieces 5Uare firmly fasthe apron n carried bythe main member andthe interlocking guides '10 and 11 hold the entire slice in vertical alinement. The slice is relatively inflexible andthus is not bowed by its weight. The bottom edge of theslice will thus be substantially horizontal at all times. A longitudinal rib 16A at the top serves as a stiiening rib preventing the slice from being bowed. One type of v auxiliary adjusting means especially adapted for use with this type of slice is the adjustable flexible bar 17 which is carried bythe loweredge24 of my.Y improved slice. The lower edge ofthe slice is substantially uniform throughout its length and a groove 25 is provided in Athe adjustable bar which is substantially the same width as the lower edge 'of the slice and the opposed walls of the vided for adjusting the bar relativel to the.

slice. Theseconsist of a plurality o spaced rods 18 the lower ends of which are seated in the bar as at 18a'. The upper end of each of the rods is threaded in the elongated shank 19 of a handwheel 23, which fits vin the recess 20 of the longitudinal rib 16. Said shank is held in position in the recess by a removable plate 21 which is fastened to the longitudiual'rib by screws 22. Each hand wheel 23 theraded on the end of each rod 18 bears against the longitudinal rib 16 and thus theportion of the bar 18 in which it is seated can be moyed and held- The hand. wheels 23 canhe locked in set position by means of a lock nut 26. Removable pieces 27 can be fastened to the main bar 17 as shown in Fig. 3. These pieces correspondin length to the width of' the complementary pieces 5a used. lThe bars 17 and '27 have cooperatin flanges 28 which may be held toget er by t(bolts 29 and thus ma e the bar sections substantiallycontinu- .ous and rigid and independent of the slice portions 5 and 5a.

In'IFigs. 2a and 2b- I show aslightly different type of flexible lip 30 which is adaptable for use with m improved slice. This flexible lip 30 is ma e of a relativelv groove thus, have close contact with the sides of the botltom edge of the slice and thus prevent stock "from passing through the jointure.

-. shown for "adjusting the lip 17.

` this type of flexible lip. These sectionsjare this pice 'of flexible marin which ils-fas tened to the bottom of the main portion of the sliceas at.24and is inclined toward the .apron board in the direction of the ilow of-- vthe paper stock and thus form's'an orifice with a stream like contour. Iprovide similar 'adjusting mechanism for this lip:4V as is Such mechanism consists of hand.. -wheels 26 which-.moves rods 18 longitudinally and thus, flex' thelip upwardly and downwardly.

Raisingthe lip causes af wider orifice 31 to be. formed between the'edge of the lip 30 and the apron board 3.

I also: provide removable sections 32 `for.

held tothe main portion of the lip` ,similar to the manner in 'whichthe removablel section. 27 is aliixed to the main portion'of the li '17, which is by companion flanges as f 33 w ich vare bolted together and thus the complementary section -form's vvan extension" -tween them, said slice consistingof a main'4 part ofl lesser length than the space between,

of the main section.
